  2. Introduction * Robert hooke (1635-1703) was the 17 th century "Natural philosopher".. * Robert hooke was born in 1635,on the Isle of wight..(Island of the southern coast of England) *The most notable discovery came in 1665 *Education is wetminster in london *published work including micrographia.
  3. Contributions • Building Telescope - In 1653 at the age of 18 ,Hooke began studying at christ church college at the university of Oxford ,where he spent much more time for building Telescope.Discovery of fifth star - one of the Hooks greatest discoveries was that of the fifth star in the trapezium of the orion constellation,in 1664. • Gregorian telescope- Hooks became one of the first scientist to build a working Gregorian telescope ,
  4. • This was the second successful reflecting Telescope designed by scottish mathematicianJamesGregory. • James Gregory was unable to make his telescope work but 10 years later ,hooke achieved his task for him. • After sir Issac newton hooke published some of his findings on low of gravity. • In 1660,Hookes discovered a physical law -Hooke's Law.
  5. • Hook's law stated that the force needed to extend or compress spring is proportional to the distance it is stretched. • The force of gravity - In a lecture in 1670,hookes correctly said that gravity applied to all celestial bodies and that the force of gravity between bodies decreases with the distance between them.If force were to be removed , the celestial bodies would move straight lines.
  6. • Hooke the Architect -while working as a scientist,hooke developed a sideline carrier as a architect .people liked his designs for buildings, and he was appointed to be surveyar to the city of the London.In fact he made much more money as an architect than as a scientist ,because he designed many of the buildings that replaced those destroyed by the great fire of London in 1666. • In 1662,hooke was given the role of curator of Experiments for the Royal society.
  7. • In 1663,he invented the 5 main metrological Instruments ,barometer,Thermometer,Hydroscope and rain gauge and wind gauge.The barometer invented by hooke was the wheel barometer.which is used to measure air atmospheric pressure. • Microscope and cell Theory- Hooke most famous work was discovery of living cell in 1665 and also hooke discovered the first known microrganism,in the form of microscopic fungi.
  8. • First to discover jupiters great red spot • Designed the " universal joint"it bends in any direction. • Designed Sash Window. • Invented cross hairs
  9. Publication • Robert hooke was a English artist,biologist,physicist,Engineer archititect and Inventor,but his crowning glory was his book Micrographia or some physiological Discriptions of minute Bodies made by magnifying glases.first published in 1665 and second published in 1667.Micrographia was a masterpiece that provided an exquisitely illustrated Introduction to the previous unknown microscopic world .The book containing large etchings of insects and plant matter in high detail inspired by his view through a microscope.
  10. • The etchings provide insight into the ornate body structure of flies ,fleas and gaints that are not visible to naked eye. • In 1745 Hentry rediscovered and reprinted as Micrographia Restaurata. • In 1678 publication of Hooke's " Lectures of spring" shared his theory of Elasticity.
  11. Honours and Awards • The hooke medal is awarded everyear by the BSCB and recognises an Emerging leader in cell biology. • The medal shows Robert hook's microscope and cork cells he first described .it was designed by Dr Brad Amos. • Nominees must have made an outstanding contribution to the cell biology and work predominantly in the uk or Ireland. • International agency for standards and Ratings celebrates 28 july as Robert Hooke Award day.
  12. • He became a fellow of the Royal society in 1663. • British historian Allen chapman refers to Hooke as "England Leonardo" • Robert hooke is known as "Renaissance man " of the 17 th century for his work in physics and biology. • Received doctor of physics degree in 1961 was named a proffessor of Geometry in 1664.
